Clarina

CLARINA, a comparatively new instrument of the wood-wind class (although actually made of metal), a hybrid possessing characteristics of
both oboe and clarinet. The clarina was invented by W. Heckel of Biebrich-am-Rhein, and has been used since 1891 at the Festspielhaus, Bayreuth, in Tristan
und Isolde, as a substitute for the Holztrompete made according to Wagner's instructions. The clarina has been found more practical and more
effective in producing the desired tone-colour. The clarina is a metal instrument with the conical bore and fingering of the oboe and the clarinet single-reed
mouthpiece. The compass of the instrument is as shown, and it stands in the key of B♭. Like the clarinet, the clarina is a transposing instrument, for
which the music must be written in a key a tone higher than that of the composition. The timbre resulting from the combination of conical bore and single-reed
mouthpiece has in the lowest register affinities with the cor anglais, in the middle with the saxophone, and in the highest with the clarinet. Other
German orchestras have followed the example of Bayreuth. The clarina has also been found very effective as a solo instrument.
